Genetic modifications to mosquitoes:
In an effort to push certain disease-carrying mosquito species to extinction, scientists are working on modifying the mosquito’s genetics. But how this could impact biodiversity—positively or negatively—remains a mystery as little is known about the role that mosquitoes play in ecosystems. Will insect-eating species feel the loss of certain mosquitoes? Do the dangerous diseases help keep other species’ populations in check?

do we have the right to choose extinction for some and not for others?

Softboxes to Go

Using diffuse flash outdoors

Unless I am working in a cave or at night, I don’t use flash outside as a prime light source.  Often  nothing beats natural light for taking flowers and other facets of the natural world; but there are times when shadows need to be in-filled. A big plus point gained by using a reflector is that you can see the effect before releasing the shutter, but on windy days, it can be a liability. I discovered the Honl Traveller 8 Softbox last year. It has an 8 inch (20 cm) diameter circular diffuser panel and having used it extensively in the UK, China and South Africa, I would never venture out without it. I use it to in-fill taller erect backlit flowers in a border where there are too many plants to use natural backlighting as the sole light source. Light from the Honl Softbox gives a much wider spread and softer light than the Sto-Fen Omni-bounce and hence casts softer shadows to inner parts of the flower; yet it also adds a certain crispness to floral parts compared to shooting in natural light, which perks up the definition of macro shots. It weighs a mere 3.7oz (105g) and folds flat in my camera photopack.

10 Species Back from the Brink

Animals that have escaped extinction

WWF have listed 10 animal species that were on the brink of extinction before habitat protection, hunting control and captive breeding programs helped to redress the balance. Photography plays an important part in public awareness of endangered species – both in their native countries and worldwide.
